  1. Serotypes and colonization factors of enterotoxigenic Escherichia coli isolated in various countries.

    Article - En anglais

    One hundred and six enterotoxigenic E. coli (ETEC) isolated from many geographical areas were serotyped and investigated for the presence of colonization factor antigens CFA/I and CFA/II, the expression of mannose-resistant haemagglutination (MRHA) and the levels of surface hydrophobicity.

    CFA/I was found in 6 (17%) of 16 LT+STa+ strains and in 15 (54%) of 28 STa+ strains; CFA/II was found in 16 (44%) of 16 LT+STa+ strains.

    None of 42 LT+strains showed CFA/I or CFA/II.

    CFA/I was found in ETEC of serotypes O61:

    • K-:H-,

    • O78:K80,

    • O128:K67 and O153:K-:H45, whereas CFA/II was found in serotypes O6:H-,

    • O6:K15:H16 and 06:K?:H40.
